The ingress PE inserts the flow label in the pseudowire packet, irrespective of the information exchanged in the signaling plane. If the egress PE cannot handle the pseudowire packet marked with the flow label, the packet is dropped.
flow-label-transmit Advertise capability to push flow label in transmit direction to the remote PE device.
flow-label-transmit-staticPush flow label on the pseudowire packets sent to the remote PE device. If the incoming pseudowire packet is not marked with the flow label, the packet is dropped by the egress PE.
